Fixed hill training

I'd quite like to do some hill climbing, the only thing that puts me off is the massive downhill ride on my brakeless roberts.... and before someone says put a brake on... my fork is not drilled.
I have ridden down highgate hill brakeless and it does get a little scary at times...

i did highgate hill on thursday. and it was fucking brilliant, but i did a lot of skidding and was backpedaling a lot too.
